IT layer
Information and business systemsEnterprise networks, user systems, business applications, data centers, cloud services, and external connections manage the flow of information.
Industrial Control Systems Security Consulting
We protect operational continuity by assessing industrial assets, IT/OT dependencies, network architecture, remote access, hardening, monitoring, and recovery as one security program.
Assess your ICS risksTwo worlds.
One operation.
Cybersecurity in industrial control systems protects not only data, but also the safe and uninterrupted operation of physical processes.
As enterprise IT and OT environments exchange data, maintenance links, remote access, supplier dependencies, and shared infrastructure create new attack paths. A weakness on either side can cause production loss, service interruption, or a process-safety risk on the other.
OT layer
Systems controlling physical processesSCADA, DCS, PLC, RTU, HMI, field devices, and engineering stations keep production and distribution processes safe and continuous.
- Operational continuity is part of every security decision.
- Every change is first evaluated for operational impact.
- IT and OT teams work with a shared risk language.
- Evidence that a control works matters as much as the control itself.
From control center to field.
Defense in depth.
ICS security cannot depend on a single product. Complementary controls—from visibility and access to network zones and recovery—must operate within one architecture.
Asset and topology visibility
SCADA, DCS, PLC, RTU, HMI, engineering stations, field devices, and IT connections are evaluated by function, protocol, version, and criticality.
Security zones and data flows
We review transitions between enterprise, DMZ, control-center, and field networks and design least-connectivity segmentation.
Identity and remote access
Operator, maintenance, and supplier access is restricted by role and made traceable with MFA, recording, time limits, and approvals.
Hardening and change management
Default accounts, unnecessary services, and unsafe settings are identified, while patches and changes are planned around production impact.
Monitoring, response, and recovery
OT-aware logging and anomaly monitoring are integrated with incident response, backup, rollback, and continuity scenarios.
Regulatory alignment and evidence
Current sector requirements, control expectations, and the organization’s criticality are reflected in the compliance plan and audit evidence.
Follow regulation.
Manage maturity.
The current EPDK approach moves ICS security beyond one-time declarations toward a measurable cyber-resilience and maturity model.
The former ICS Information Security Regulation dated 2017 and numbered 30123 has been repealed. Work should be based on the current Competency Model, sector-specific technical controls, and other applicable requirements.

- Sector-specific technical controls and reference topologies
- Compliance plan, activity evidence, and progress reporting
- Readiness for independent audits, including field controls
- A management-system structure that can be mapped to ISO 27001 controls
Field and architecture discovery
Critical processes, assets, connections, remote access, and IT/OT dependencies are identified using production-safe methods.
Risk and control analysis
Architecture, operating processes, and applicable requirements are compared and risks are prioritized by operational impact.
Secure transformation design
A practical target architecture is defined for segmentation, access, hardening, monitoring, backup, and response.
Implementation and validation
Controls are deployed through planned maintenance and change management, then evidence and test results are tracked.
Produce the outcome.
Preserve the evidence.
The engagement produces more than a recommendation list: it creates a concrete security structure that teams can implement and demonstrate during an audit.
- IT/OT asset and dependency view
- Network topology and zone analysis
- ICS risk and control assessment
- Secure remote-access model
- Hardening and change recommendations
- Monitoring and incident-response requirements
- Regulatory compliance gaps

Frequently asked
questions.
Is ICS security the same as traditional IT security?
No. Physical process safety, availability, real-time operation, long device lifecycles, and planned maintenance require different decisions.
Do the same controls apply to every energy organization?
No. Minimum requirements vary by criticality, sector model, and applicable regulation.
Can a security assessment interrupt production?
Methods are selected by operational risk. Passive discovery, maintenance windows, approvals, and rollback plans minimize production impact.
Is fully separating OT from IT enough?
No. Segmentation must work with identity, remote access, hardening, monitoring, response, backup, and supplier management.
